<BLOCKQUOTE>Visitor for type safe operations on osg::Node's.
Based on GOF's Visitor pattern. The NodeVisitor 
is useful for developing type safe operations to nodes
in the scene graph (as per Visitor pattern), and adds to this
support for optional scene graph traversal to allow
operations to be applied to whole scenes at once. The Visitor
pattern uses a technique of double dispatch as a mechanism to
called the appropriate apply(..) method of the NodeVisitor.  To
use this feature one must use the Node::accept(NodeVisitor) which
is extended in each Node subclass, rather than the NodeVisitor
apply directly.  So use root->accept(myVisitor); instead of
myVisitor.apply(*root).  The later method will bypass the double
dispatch and the appropriate NodeVisitor::apply(..) method will
not be called. </BLOCKQUOTE>

<DD>Set the TraversalMask of this NodeVisitor.
The TraversalMask is used by the NodeVisitor::validNodeMask() method
to determine whether to operate on a node and its subgraph.
validNodeMask() is called automaticaly in the Node::accept() method before
any call to NodeVisitor::apply(), apply() is only ever called if validNodeMask
returns true. Note, if NodeVisitor::_traversalMask is 0 then all operations
will be swithced off for all nodes.  Whereas setting both _traversalMask and
_nodeMaskOverride to 0xffffffff will allow a visitor to work on all nodes
regardless of their own Node::_nodeMask state.
